How TFT Displays WorkTFT displays or thin film transistor displays utilize simple chemical and electrical properties to create a visible image on a screen. Utilizing an electrical charge that causes the liquid crystals to change their molecular structure allowing various wavelengths of backlight to “pass-through”. The active matrix of the TFT display is in constant flux and changes or refreshes rapidly depending upon the incoming signal from the control device.

The TFT panel utilizes several layers of filters sandwiched between two glass panels. Two polarizer filters, color filters and two alignment layers determine exactly how much light is allowed to pass and which colors are created. The TFT layer controls light flow a color filter displays the color and a top layer houses your visible screen.

The pixels of TFT displays are determined by the underlying density of the color matrix and TFT layout. The more pixels the higher detail is available. Available screen size, power consumption needs, and product needs define the TFT displays recommended for your company’s project.

Standard TFT displays utilize a back-light of white bright light to generate the picture. Newer panels utilize LED or light emitting diodes to generate their light and therefore utilize less power and require less depth by design. The TFT displays utilized by Shelly Inc are leading edge technologies adapted to your project needs and combined with our built in graphic processors.
